[Maintenance] - Clear Form State only on Cancel

[staysgt]

Description

When you click outside a task (or hit escape), our NERModal closes and the form resets, same as hitting cancel button. This keeps happening by accident. Form state shouldn't clear unless the user explicitly clicks 'cancel'.

Acceptance Criteria

• clicking outside the modal or pressing escape no longer closes it or clears the form; only clicking cancel does

Proposed Solution

• in NERModal.tsx, change Dialog's onClose={onHide} to receive (event, reason) and ignore backdropClick/escapeKeyDown instead of always calling onHide
